Resumo: A digestion trial was conducted with sheep to determine the nutritive value of Siratro (Phaseolus atropurpureus) hay, at different vegetation stages. The total collection technique was used. The following variations in the crude fractions were observed: dry matter: 81.42-90.36%; protein: 13.82-17,97%; ether extract: 1.88-3.01%; fiber: 33.16-40,69%; minerals: 7,14-15.78% and nitrogen free extract: 22.53-39.5% .Average crude protein content was higher than for other tropical legumes. The observed digestibility coefficients were as follows: dry matter, 41.95-70,55%; protein, 67.18-81.1%; ether extract, 31.90-75.28%; fiber, 31.23-65.94% and nitrogen free extract, 48.61-78.45%. Digestibility coefficients for crude protein and crude fiber and digestible protein on dry matter basis were higher in hays from plants at more advanced stage of vegetative growth. Significant differences (p<0,05) were detected in TDN among different stages. The variation observed was 44.44-69.99%. The highest intake of TDN by the animals was associated with hays cut at the more advanced vegetative stages.

O feno de Siratro apresentou a seguinte variação na fração bruta: matéria seca, 81,42 a 90,36%; proteína, 13,82 a 17,97%; extrato etéreo, 1,88 a 3,01%; fibra, 33,16 a 40,69%; minerais, 7,14 a 15,78%, e extrato não nitrogenado, 22,53 a 39,50%. O teor médio de proteína bruta foi relativamente alto, quando, comparado ao de outras leguminosas tropicais. A variação dos coeficientes de digestibilidade foi a seguinte: matéria seca, 41,95 a 70,55%; proteína, 67,18 a 81,10%; extrato etéreo, 31,90 a 75,28%; fibra, 31,23 a 65,94%, e extrato não nitrogenado, 48,61 a 78,45%. Os coeficientes de digestibilidade da proteína e da fibra e a proteína digestível na matéria seca foram mais altos nos fenos provenientes de plantas em estádio mais avançado do ciclo vegetativo. Foram observadas diferenças significativas (p<0,05) entre os cortes para os nutrientes digestíveis totais (NDT). Os teores encontrados variaram de 44,44 a 69,99%. O maior consumo de NDT pelos animais também foi relacionado aos cortes efetuados num estádio mais avançado da planta. A relação nutritiva mais estreita foi encontrada em plantas com floração e vagem em formação e a mais ampla, na primavera, com Siratro em floração.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraLima, Carlos RodriguesSouto, Sebastião ManhãesGarcia, José Maurício ReisAraújo, Maria Ribeiro2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17425Pesquisa Agropecuaria Brasileira; v.7, n.1, 1972: Série Zootecnia; 63-66Pesquisa Agropecuária Brasileira; v.7, n.1, 1972: Série Zootecnia; 63-661678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17425/11688info:eu-repo/semantics/openAccess2014-04-15T18:39:21Zoai:ojs.seer.sct.embrapa.br:article/17425Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T18:39:21Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
